    Q: What is the definition of BoLo, NoLo, and LoLo?

    BoLo: Block zero loader - The lowest level bootloader or bootstrap code on the system. BoLo was incorporated into LogicLoader code after LoLo version 1.4.0 and no longer exists as stand-alone code.
    NoLo: NAND Loader - The job of NoLo is to load and execute LoLo. NoLo always resides at block zero, and uses no more than one block of the NAND device. Block zero is guaranteed by the NAND device manufacturer to be a good block for the life of the device. NoLo is only present on SOMs that support booting from NAND.
    LoLo: LogicLoader - A full-featured bootloader that includes networking and a full command set.
